Abstract
DISPOSITIVO DE SISTESIS Y DE DESMODULACION DE FRECUENCIA PARA RECEPTOR DE ONDAS PORTADORAS MODULARES EN FRECUENCIA. COMPRENDE DOS BUCLES DE ENCLAVAMIENTO DE FASE QUE ACTUAN SOBRE UN OSCILADOR LOCAR (150) DE FRECUENCIA VARIABLE MANDADO POR TENSION. EL PRIMER BUCLE (110), DE SINTESIS DE FRECUENCIA CLASICA, SELECCIONA AQUELLA DE LAS ONDAS RECIBIDAS CUYA SEÑAL MODULANTE DEBE SER RESTITUIDA Y ESTA COMBINADO CON EL SEGUNDO BUCLE (120), DE DESMODULACION CLASICO, QUE RESTITUYE, POR UNA PARTE, UNA AL MENOS DE LAS ONDAS PORTADORAS MODULADAS, Y POR OTRA PARTE, LA ONDA SUMINISTRADA POR EL OSCILADOR.
